New Material

Anactolasma yukonanum new genus and species is described from the Pragian of Yukon Territory and is assigned to the Anactolasmatinae, a new subfamily of the Mucophyllidae Hill. Adult stages of Anactolasma resemble gerontic stages of Kobeha Merriam, although the genera have distinct ontogenies. Kobeha is revised on the basis of new material of its type species K. walcotti Merriam. The Papiliophyllinae Stumm are promoted to family status. Kobeha ketophylloides Merriam, from the Pragian of Nevada, and Endophyllum banksi Jell and Hill, from the Pragian of Tasmania, are restudied using new topotypic and other material. A new endophyllid genus named Murphyphyllum is erected for them, with E. banksi as type species. Asarcophyllum ramosum new genus and species, from the Emsian of Nevada, is made type species of a new cyathophyllid genus. Spongophyllum nevadense Stumm and S. expansum Stumm, both also from the Emsian of Nevada, are placed in the new genus, as is Asarcophyllum corona new genus and species, from the Emsian of Yukon Territory. Biostratigraphic settings, with emphasis on associated corals, brachiopods and conodonts, are given for the new and revised genera and species.

New Genus And Species

Dinnebitodon amarali, a new genus and species of Tritylodontidae, is described from the Early Jurassic Kayenta Formation of northeastern Arizona. It is distinguished from Kayentatherium wellesi by the possession of three (rather than one) upper incisors and upper postcanine teeth with two (rather than three) lingual cusps.

Baiotomeus is a new genus of ptilodontid multituberculate from the late Torrejonian Land-Mammal Age (late middle Paleocene) of western North America. Baiotomeus douglassi (Simpson), the type species, has been assigned, at one time or another, to Ptilodus, Mimetodon, and Neoplagiaulax. In addition, a second, new species, B. lamberti, from three localities in the Medicine Rocks area of southeastern Montana is reported here. The Medicine Rocks localities are tentatively assigned a latest Torrejonian age, younger than localities yielding B. douglassi and younger than previously suggested on the basis of plesiadapid primates.Multituberculates appear to have attained their highest species richness during the Torrejonian Land-Mammal Age, but the discovery of B. lamberti illustrates that our knowledge of multituberculate diversity is incomplete from even that interval of time.

Fruit Surface

A new kind of fin-winged fruit is recognized from lacustrine shales of the early Eocene Tepee Trail Formation of northwestern Wyoming and from the middle Eocene Clarno Formation of central Oregon, USA. The fruits are obovate with five thick lateral wings, borne on a thick pedicel and bearing scars of hypogynous perianth and disk. The fruit surface is covered with small circular dots interpreted as glands. This combination of characters leads us to infer affinities with the Rutaceae, although no identical modern genus is known. We establish the new genus and species, Quinquala obovata.

A New Species

AbstractA new genus and species, Sacculozetes filosus, is described from riparian grassland in the Soviet Far East, and a new species, Guatemalozetes danos, is described from shortgrass and alpine prairie in western North America, both on the basis of adults. The genus Guatemalozetes Mahunka is redefined; this is the first record of this genus from temperate North America. A close relationship is indicated between Sacculozetes and Lamellobates Hammer, Paralamellobates Bhaduri and Raychaudhuri, and Hypozetes Balogh. The uncertain family placement of Sacculozetes and Guatemalozetes within the Ceratozetoidea is discussed. Adults of both genera exhibit character states of the Mycobatidae, but until immatures are discovered, they are considered unplaced genera in the superfamily.

TRANSFER OF THE TARSOCHEYLIDAE TO THE HETEROSTIGMATA, AND REASSIGNMENT OF THE TARSONEMINA AND HETEROSTIGMATA TO LOWER HIERARCHIC STATUS IN THE PROSTIGMATA (ACARI)

New Synonymy

AbstractThe systematic status of the genus Tarsocheylus Berlese, 1904 and the position of the family Tarsocheylidae Atyeo and Baker, 1964 in the Prostigmata is reviewed. The family does not belong in either the Raphignathoidea or the Anystoidea but in its own superfamily, the Tarsocheyloidea, which is described for this purpose. In turn, this superfamily is placed alongside the Heterocheyloidea in the Heterostigmata.Because the type-species of Tarsocheylus, T. paradoxus Berlese, 1904, is conspecific with Hoplocheylus discalis Atyeo and Baker, 1964 (new synonymy), the concept of Hoplocheylus Atyeo and Baker, 1964, which has remained until now as originally proposed, is the same as that of Tarsocheylus. However, a new case is made for recognizing these genera as mutually distinct, based on other morphological criteria. Tarsocheylus atomarius Berlese, 1913, the type-species of Hoplocheylus, is apparently conspecific with Hoplocheylus canadensis Marshall, 1966 (new synonymy) and perhaps with one or two other described species from North America. A third generic entity, represented by Hoplocheylus johnstoni Atyeo and Baker, 1964, is noted but not named or formally described. Hoplocheylus pickardi Smiley and Moser, 1968 is conspecific with H. similis Delfinado and Baker, 1974 (new synonymy).Hemitarsocheylus Soliman and Zaher, 1975, which was described as a new genus in the Tarsocheylidae, is congeneric with Stigmocheylus Berlese, 1910 (new synonymy). This genus does not belong in the Tarsocheyloidea, but rather in the Anystoidea.A list of character states found useful in recognizing groupings of species of Tarsocheylidae is presented. Based on the collection data with specimens representing described and undescribed species at hand, the known distribution of the Tarsocheylidae is extended to include Australia and western North America, and the second known instance of an association with passalid beetles is recorded.From a phylogenetic standpoint, the Tarsocheyloidea and Heterocheyloidea are proposed as sister groups that together constitute a new suprafamilial taxon, the Tarsocheylina. In turn, the Tarsocheylina and Tarsonemina are proposed as sister groups, and both are described; together, they form the Heterostigmata.The systematic and phylogenetic relationships of the Heterostigmata (including the Tarsonemina) to the Prostigmata and the Astigmata are reviewed. Not only should the Heterostigmata be retained in the Prostigmata but it should be lowered in hierarchic rank, such that it is a part of the Eleutherengona. The stock that gave rise to the Anystoidea and related superfamilies is shown to be ancestral to the Heterostigmata as well.

AbstractWe describe the first dragonflies (Odonata: Anisoptera) from the early Eocene Okanagan Highlands of far-western North America from nine fossils. Six are assigned to five species in four new, named genera of Aeshnidae: Antiquiala snyderaenew genus and species, Idemlinea versatilisnew genus and species, Ypshna brownleeinew genus and species, Ypshna latipennatanew genus and species, and Eoshna thompsonensisnew genus and species; we treat one as Aeshnidae genus A, species A; one is assigned to Gomphidae: Auroradraco eosnew genus and species; and we treat a ninth, fragmentary fossil of unknown family affinity as Anisoptera indeterminate genus A, species A, which represents a seventh genus and eighth species. The dominance of Aeshnidae is consistent with other Paleocene and Eocene fossil localities. Auroradraco eos is the only fossil Gomphidae in the roughly 66-million-year gap between occurrences in mid-Cretaceous Burmese amber and the early Oligocene of France. Ypshna appears close to Parabaissaeshna ejerslevense from the early Eocene Fur Formation of Denmark; this is not surprising given Holarctic intercontinental connections at this time and a growing list of insect taxa shared between the Okanagan Highlands and the Fur Formation.

AbstractSertulaster keslinginew genus new species (Palaeasteridae) andDelicaster hotchkissinew species (Permasteridae) are asteroid echinoderms described, respectively, from the Ordovician and Carboniferous of eastern North America. The new genus and species help to document diversity within taxa of lower rank.S. keslingiis similar to the Early OrdovicianEriasterBlake and Guensburg, 2005 but exhibits less differentiation of the skeletal elements from beyond the ambulacral column, that of the so-called extraxial skeleton, whereas the comparatively robust construction ofDelicaster hotchkissiclearly departs from that of the type species,D. enigmaticus(Kesling, 1967). Small sample sizes and incomplete exposure of available specimens illustrate ambiguities typically encountered in the study of fossil asteroids.UUID:http://zoobank.org/fb44075c-396b-4f95-b997-29cdf3c4f3c1
